fix(sisyphus-orchestrator): inject delegation warning before Write/Edit outside .sisyphus

- Add ORCHESTRATOR_DELEGATION_REQUIRED strong warning in tool.execute.before
- Fix tool.execute.after filePath detection using pendingFilePaths Map
- before stores filePath by callID, after retrieves and deletes it
- Fixes bug where output.metadata.filePath was undefined

+**STOP. YOU ARE VIOLATING ORCHESTRATOR PROTOCOL.**
+
+You (orchestrator-sisyphus) are attempting to directly modify a file outside \`.sisyphus/\`.
+
+**Path attempted:** $FILE_PATH
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+🚫 **THIS IS FORBIDDEN** (except for VERIFICATION purposes)
+
+As an ORCHESTRATOR, you MUST:
+1. **DELEGATE** all implementation work via \`sisyphus_task\`
+2. **VERIFY** the work done by subagents (reading files is OK)
+3. **COORDINATE** - you orchestrate, you don't implement
+
+**ALLOWED direct file operations:**
+- Files inside \`.sisyphus/\` (plans, notepads, drafts)
+- Reading files for verification
+- Running diagnostics/tests
+
+**FORBIDDEN direct file operations:**
+- Writing/editing source code
+- Creating new files outside \`.sisyphus/\`
+- Any implementation work
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+**IF THIS IS FOR VERIFICATION:**
+Proceed if you are verifying subagent work by making a small fix.
+But for any substantial changes, USE \`sisyphus_task\`.
